Hi Mark, I installed Nevada build 124 on my Ultra 45 today (replacing Solaris 10). Yesterday I was trying OpenSolaris b123 autoinstall image, but b123 is broken on SPARC, so I switched to Nevada today. The results:
1) b123 on OSol supported all 3 frequencies (50MHz, 800MHz and 1.6GHz) and in poll-mode I saw it working well 2) b124 - kstat cpu_info says only 1.6GHz is supported + WARNING: cpudrv_attach: instance 0: can't gate cpu_t Best regards, Milan Mark Haywood p??e v st 30. 09. 2009 v 05:27 -0400: > Can you provide me with the output from 'kstat cpu_info'? > > Thanks, > Mark > > Jedy Wang wrote: > > Hi Mark, > > > > Please see my comments inline. > > > > > >> Interesting.
